Joe Biden is having the worst time getting his offices right this week.

While taking a victory lap after the South Carolina primary on Saturday, he told a crowd of supporters that the Senate candidate there is running for president.

“Folks, now we need to stand behind Jaime Harrison, the next president of the United— next senator,” Biden said.

Earlier this week, Biden told an audience he is a candidate for the U.S. Senate.

“You’re the ones who sent Barack Obama the presidency. And I have a simple proposition here: I’m here to ask you for your help. Where I come from, you don’t go very far unless you ask. My name’s Joe Biden. I’m a Democratic candidate for the United States Senate,” he said.

Biden continued, “Look me over. If you like what you see, help out. If not, vote for the other Biden. Give me a look though, okay?”

He never corrected his error.
